Technical Field

[0001] The utility model relates to the field of junction boxes, in particular to an outdoor junction box for building electrical circuits. Background Art

[0002] The junction box is one of the electrical auxiliary materials, because the wires used for decoration pass through the wire tube, and the junction box is used as a transition at the joint of the wires (for example, the line is relatively long, or the wire tube needs to turn a corner). The wire tube is connected to the junction box, and the wires in the wire tube are connected in the junction box. The junction box is composed of a box cover, a box body, and a connector. It must have a waterproof sealing design, scientific anti-electric shock insulation protection, and better safety performance; the terminal blocks must be installed firmly and have good weldability with the busbar.

[0003] However, since the distance between the connector in the junction box and the side end of the box body is relatively short, it is troublesome to perform the connection after threading. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an outdoor junction box for building electrical circuits, which solves the problems mentioned in the above background.

[0006] As a further solution of the utility model: the upper surface array of the wiring seat is provided with wire clamping seats, and the wiring bolts are installed above the wire clamping seats.

[0007] As a further solution of the utility model: an upper cover is arranged above the junction box, a waterproof strip slot is opened on the inner side wall of the upper end of the junction box, a wire threading tube is installed on the side surface of the junction box, and a sealing wire sleeve is installed on the outer side of the wire threading tube.

[0008] As a further solution of the utility model: the depth dimension of the positioning through hole is greater than the length dimension of the positioning rod, and the clamping block is clamped with the buckle block.

[0009] As a further solution of the utility model: the magnetic pad is fixedly connected to the wiring seat through the spring, and the magnetic pad is magnetically fixed to the magnetic block.

[0012] As a further solution of the utility model: the wire threading tube is arranged through the junction box, and the wire sealing sleeve is engaged and fixed with the wire threading tube.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 2-5 As shown, in this embodiment, the upper surface array of the terminal block 3 is provided with a wire clamping seat 302, and the upper part of the wire clamping seat 302 is installed with a wiring bolt 301, and the wiring bolt 301 is engaged and fixed with the terminal block 3, and an upper cover 2 is arranged above the terminal box 1, and a waterproof strip card slot 6 is provided on the inner side wall of the upper end of the terminal box 1, and a waterproof gasket is installed at the position of the waterproof strip card slot 6 on the lower surface of the upper cover 2, and a wire threading tube 4 is installed on the side surface of the terminal box 1, and the wire threading tube 4 is arranged through the terminal box 1, and a sealing wire sleeve 5 is installed on the outer side of the wire threading tube 4, and the sealing wire sleeve 5 is engaged and fixed with the wire threading tube 4.

[0025] The working principle of the utility model is as follows: when wiring is required, the two ends of the connected cables are respectively inserted into the interior of the wiring box 1 from the threading tubes 4 at the two sides of the wiring box 1, and the wiring seat 3 is taken out from the interior of the wiring box 1 as a whole.

At the same time, the positioning rod 102 inside the junction box 1 will be squeezed toward the inside of the positioning through hole 305 as a whole, controlling the spring 306 to deform and shrink. Finally, after the upper cover 2 is covered on the upper end of the junction box 1, the upper cover 2 and the junction box 1 are fixed by bolts.
